realtek phy 8211fs相关配置

boot：手动

1.自协商

mii write port_id 1f 0x0a43
mii write port_id  1b 0xdc88
mii read port_id  1c
mii write port_id  1b 0xdc88
mii write port_id  1c 0x074b

2.配置TXDLY enable

mii write port_id 1f 0xd08

mii write port_id  10 0x5e

/*d08页寄存器0x11，第8bit要设置为1，否则不能正常收发包*/

mii write port_id  11 0x109

mii write port_id  1f 0 (归零)

但是目前遇到问题没有RX信息，这就搞不懂了，网口驱动还是比其他驱动复杂多了...
